Addis Ababa Business Pulse

Culture Diplomatic and growing rapidly. Home to the African Union.
Lunch Break 12:30 PM - 1:30 PM.
Pro Tip Ideal window for calls is 9:30 AM to 12:00 PM. Ethiopia uses its own unique 12-hour clock (counting from 6 AM as "Hour 1"); always clarify "European Time" or "GMT/UTC" when scheduling to avoid confusion. Business is polite, formal, and values personal trust.

Hanoi Business Pulse

Culture Formal, hierarchical, and relationship-driven. Government presence is strong.
Lunch Break 12:00 PM - 1:30 PM.
Pro Tip Best reached between 9:00 AM and 11:30 AM. Business in the capital is more formal and hierarchical than in the south. Relationships with authority and government are often important. Trust must be built through multiple polite interactions and formal introductions.
